The vehicle locking device 1 is used for receiving a vehicle locking instruction and a vehicle unlocking instruction sent by the controller 2, locking a vehicle according to the received vehicle locking instruction, and the vehicle cannot run; and unlocking the vehicle according to the received unlocking command, so that the vehicle can normally run. In this embodiment, the locking device is separately provided, for example, the locking device is a mechanical locking device provided on a wheel of the vehicle, the locking device is locked when receiving a locking command to disable the vehicle from running, and the unlocking device is unlocked when receiving a unlocking command to enable the vehicle to run normally; as another embodiment, the vehicle defrosting system may not be provided with a locking device separately, but may implement locking or unlocking of the vehicle in a software Control manner, for example, the controller sends a locking command or an unlocking command to an engine ECU (Electronic Control Unit), and the engine ECU controls the locking or unlocking of the engine according to the received corresponding command, so as to implement locking or unlocking of the vehicle.
The frosting sensor 3 is arranged on the vehicle glass and used for detecting the frosting phenomenon of the vehicle glass and sending the detection result to the controller 2. The frosting sensor may be of an optical type, a capacitive type or a mechanical type. In general, the front windshield of the vehicle needs to be defrosted, so in this embodiment, two frosting sensors are respectively arranged on the windshield (i.e. the front windshield) right in front of the main driver and the assistant driver; of course, if defrosting of other glass on the vehicle is required, the number and arrangement positions of the frosting sensors can be determined according to actual requirements. In the embodiment, the frosting sensor is utilized to realize accurate detection of the frosting phenomenon of the vehicle glass, the accuracy is higher compared with artificial subjective judgment, automatic defrosting of the vehicle glass can be realized when the frosting phenomenon of the vehicle glass is detected, a driver is effectively prevented from driving the vehicle when not defrosting, and the driving safety is improved; in other embodiments, the vehicle defrosting system may not be provided with a frosting sensor, and in this case, the frosting phenomenon of the vehicle glass needs to be judged by people.
The spray device 4 is used to spray the defrosting liquid, which has been increased in temperature by passing through the heater 6, onto the glass of the vehicle under the control of the controller 2. The spraying mode of the spraying device can be spraying, sprinkling, spraying or the like. In the present embodiment, the ejection device is provided near the front windshield to defrost the front windshield; of course, the spraying device can also be arranged near other vehicle glass needing defrosting according to actual needs.

The heater 6 is used to heat the defrost liquid under the control of the controller 2.
In this embodiment, both the power of the water pump and the power of the heater are adjustable, and accordingly, there are 3 implementation manners as follows for the controller to control the temperature of the defrosting liquid flowing through the heater to gradually rise, and in the actual application process, any one of the 3 manners can be selected according to actual needs (the manner (3) corresponding to fig. 2).
Mode (1): the controller controls the water pump to work at constant power, and simultaneously, the power of the heater is gradually increased. At this time, the flow rate of the defrosting liquid flowing through the heater is not changed, but the heating rate of the defrosting liquid by the heater is gradually increased, that is, the volume of the defrosting liquid flowing through the heater per unit time is the same, and the temperature at which the same volume of the defrosting liquid is heated per unit time is proportional to the heating rate, so that the temperature of the defrosting liquid sprayed by the spraying device is gradually increased when the heating rate is gradually increased without changing the flow rate.
Mode (2): the controller controls the heater to work at constant power, and simultaneously, the power of the water pump is gradually reduced. At this time, the heating speed of the defrosting liquid by the heater is not changed, but the flow rate of the defrosting liquid flowing through the heater is gradually reduced, that is, the volume of the defrosting liquid flowing through the heater in unit time is gradually reduced, and the temperature of the defrosting liquid sprayed by the spraying device is gradually increased under the condition that the heating speed is not changed and the flow rate is gradually reduced because the temperature of the defrosting liquid is higher under the same heating speed as the volume of the defrosting liquid in unit time is smaller.
Mode (3): the controller adjusts the power of the water pump and the power of the heater in real time, the water pump and the heater are matched with each other, the temperature of the defrosting liquid sprayed by the spraying device is gradually increased, and for example, the controller gradually increases the power of the heater while gradually reducing the power of the water pump.
Wherein the water pump is not necessary for the vehicle defrost system, but may be provided according to actual needs, for example, when the position of the water tank is higher than the position of the spray device, the vehicle defrost system may not be provided with the water pump. When the water pump is not arranged or the water pump is arranged but the power of the water pump is not adjustable, the controller changes the heating speed of the heater to the defrosting liquid by adjusting the power of the heater, and further the temperature of the defrosting liquid flowing through the heater is controlled to be gradually increased; when the water pump is arranged and the power of the heater is not adjustable, the controller changes the flow rate of the defrosting liquid flowing through the heater by adjusting the power of the water pump, and further the temperature of the defrosting liquid flowing through the heater is controlled to be gradually increased.
The temperature sensor 7 is used to detect the temperature of the defrosting liquid ejected by the ejection device 4 and send the temperature to the controller 2. The defrosting device comprises a heater, a temperature sensor, a controller and a controller, wherein the heater is arranged in the heater, the temperature sensor is arranged, the temperature sensor is used for detecting the temperature of defrosting liquid sprayed by the spraying device in real time, and when the temperature reaches a set temperature, the controller controls the defrosting liquid flowing through the heater to keep the set temperature so as to realize constant-temperature defrosting and ensure good defrosting effect. The implementation mode that the controller controls the defrosting liquid flowing through the heater to keep the set temperature is determined by the implementation mode that the controller controls the temperature of the defrosting liquid flowing through the heater to be gradually increased, for example, when the implementation mode that the controller controls the temperature of the defrosting liquid flowing through the heater to be gradually increased is the mode (1), the defrosting liquid flowing through the heater keeps the set temperature by controlling the constant-power work of the heater; when the mode (2) is adopted, the defrosting liquid flowing through the heater is kept at the set temperature by controlling the constant-power work of the water pump; in the case of the mode (3), the defrosting liquid flowing through the heater is maintained at the set temperature by controlling the water pump and the heater while maintaining the constant power operation. In this embodiment, the temperature sensor is provided, and the temperature sensor is used to detect whether the temperature of the defrosting liquid sprayed by the spraying device reaches the set temperature in real time.
